ROLLER-SKATE.

SPBCIFICATIQN forming part of Letters Patent No. 332,181, dated December 8, 1885.

Application filed February 28, 1885. Serial No. 157,400. (No model.)

To all whom it may concern.-

Be it known that I, FRED A. BAILEY, a citizen of the United States, residing at Oakland, in the county of Kennebeo and State of Maine, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to roller-skates and the object of my invention is to produce a skate wherein the bearing shall at all times be entirely on a spring or cushion of rubber. I accomplish this result by means of the mechanism illustrated in the accompanying drawings, in which Figure l is a side elevation. Fig. 2 is a side section through y y of Fig. 3. Fig. 3 is a section in perspective through as x of Fig. 2.

B is a box or guide,set at an angle with the floor and having an opening on each side, within which is placed the roll-carrier A. The opening in the sides of box B are considerably larger than roll-carrier A.

A is a block having a notch on its upper and under sides of the same width as the interior of the box B. The spindle which carries the rolls passes through it from end to end. Two blocks of rubber, G 0, one above and one below A, are placed in the interior of the box B and fit into the notches on the rollcarrier A. The under piece just fills its place.

That portion of the box B which is above the roll-carrierA is made longer than that be low, and the rubber C does not completely fill that space out to the end of the box. The screw E passes through the end of the box and impinges against the plate D, which plate rests against the rubber C.

It will thus be seen that when the skate is in position the rubber 0 forms a bearing for the roll-carrier, and the two rubbers O and 0, together with the guides formed by the sides of the box B, confine and limit the motion of the roll-carrier. The weight is at all times taken by the rubber C, and not by a rigid axis, as in the ordinary roller-skates. \Vhen the weight is on one side,the roll-carrier is free to incline by compressing the rubbers O G on their edges. By the use of the screw E the rubber C may be compressed or loosened,thus making the inclination of the roll carrier more or less dificult.

Then it is desired to remove or put in the roll-carrier, the screw E is drawn back,lcaving the rubber U and plate D free to be pushed back into the recess in the upper end of box B. There is then room between the two rubbers O and O to draw out the roll-carrier. The rubbers O C may be replaced by springs of metal.

I claim I n a roller-skate, the notched roll-carrier A, working in the inclined guide or box B and supported by the springs O O, substantiallyas set forth and described.

In testimony whereof I affix my signature in presence of two witnesses.

FRED A. BAILEY.
